Sorry for the late reply, was a very stressful week so far....
Sorry, can't see any of your photos. I see they are links to googlecontent but even when I copy them into another browser it won't show anything.
That's strange! I can see all of them fine, but then again I am the source of the photos (my Google account). Is there any other way I could post photos? Maybe an Imgur link or something? It doesn't look like I can upload photos directly.
Funny that you come up with 3D printing covers as I just gave a friend around a dozen of them like 2 weeks ago. So far He only finished the button cell cover for the Sharp PC-3000 and the button cell cover for the Memorex. Actually we wanted to make replicas of pretty much every battery cover and port latch that we can. Due to having like 40ish palmtops in my collection you guess that I'm also missing loads of these for various palmtops...
Nice! If you get them for the Gradebook I'd appreciate it if you could send me the .stl file for 3D printing.
I just got the Gradebook out. And I can see the trouble.
Well you have seen the BIOS option. I think if you load config.sys from ROM the option is always REMed out, unfortunately. I must admit I think I only used it with SRAM cards. Then you can obviously put any system and config on the card that you like to. I definitely DID use CF with their evil twin - the LC-8600, but as these came with a harddisk editing config.sys was obviously easier.
That really sucks. I tried the BIOS PC card boot option (with 32MB CF inserted, containing copies of config.sys with "device=sdpdrv.sys" and autoexec.bat) with no success, but I might not have been paying close enough attention. What drive should the CF card be? A? B? F?
I ended up having to stop playing around with the CF card last night due to an unexpected problem. For some reason last night, I had trouble resetting the palmtop - after putting in the batteries I just get all the status LEDs on continuously, even after pressing down the reset button for a long time. I also had this problem when I first tried out the palmtop, but pressing the reset button for a while did the trick...probably after an hour of trial and error. I wonder if there is a bad cap in the reset circuit, or something else. I'd like to hear your thoughts.
No idea why sdpdrv.sys is commented out. It doesn't seem to make much sense. I think there was a tool called "DEVLOD" that you could use to load drivers AFTER boot. Gotta see if I still have it on some old backup. If you have an SRAM card you could just boot from that first.
I do have a 2MB SRAM card (as well as 256K and 1MB). If I can somehow get the needed files on that, I would just boot(strap) from it and then switch to CF. Also DEVLOAD sounds really good. It might be easiest to transfer that to the RAM drive and go from there.
Oh well, I guess I could always burn another EPROM (hahaha - too hard), if I ever figure out which one is the C drive and what the model number is (I don't think config.sys/autoexec.bat is on the 27C4000 EPROM).
On a side note - on C: there's the absetup tool which lets you disable unwanted ports and such stuff to save some power.
Yes, I used that to turn off the parallel port.
If I don't forget imma take some photos later. If my buddy has already made some slt for the lexicomp I can also send you that.
Yes, .stl files would be great! Both for the port latch and battery cover. Thank you so much! Time to use my 3D printing coupon (200g or something for free) at my local makerspace!
